A story about research at Old Dominion University, where participants are paid to ride an exercise bike so that researchers can study the affect on everything from blood pressure to weight loss, mentions a study by professor Barry Franklin at the Wayne State University School of Medicine and David Swain, an exercise science professor at Old Dominion. They found that vigorous exercise lowered the risk of heart disease more than did moderate-intensity exercise. It also more positively affected diastolic blood pressure readings, glucose control and aerobic capacity.
